BRUSSELS (AP) — European Union nations have again failed to bridge bitter disagreements over a natural gas price cap as they struggle to effectively shield 450 million citizens from massive increases in their utility bills as cold weather sets in. An emergency meeting of energy ministers Thursday only showed how the energy crisis tied to Russia’s war in Ukraine has divided the 27-nation bloc in almost irreconcilable blocs. Ministers couldn’t agree on when and how a price cap on gas purchases should kick in. Nations including Greece, Spain, Belgium and France are demanding cheaper gas to ease household bills. Germany, the Netherlands and others insist supplies are at risk if a cap stops EU countries from buying gas above a certain price.
